Lithium production wasnât always this simple, or this cheap. For almost half a century, starting in the early 1950s, the worldâs primary source of lithium was North Carolina, much of it from a mine in the town of Kings Mountain.
Argentina also produces lithium from brine at the Hombre Muerto Salt Flat. There is also an enormous lithium deposit in Bolivia at the Uyuni Salt Flat (the world's largest salt flat), but this resource remains untapped for now due to political and economic reasons. The largest producer of lithium from spodumene is Australia, which has a large deposit near Perth. Other major lithium producers include China, which produces it at salt lakes in Tibet and Qinghai, and the United States, which produces it from brine in Nevada.
